SU28775A1 - Device for winding a film on the bottom reel - Google Patents

Description

The author's certificate no. 28774 describes various forms of making a device for automatically winding a film on a lower bobbin. In one of them, the reel is put on freely on the rotating roller and captured by it, thereby eliminating the need for a spring, typically used to secure the reel to the roller. In another device, the shaft axis is mounted on ball bearings and an eccentric bushing with a screw is used to adjust the tension of the drive belt on the pulley. In the remaining devices, springs and additional rollers are used for additional friction.

The proposed fixture represents, in several ways, a further improvement of the fixture described in the author's certificate No. 28774.;

In FIG. 1 depicts a cross section of the device described in paragraph 3 of the main copyright certificate, but in a different form of execution: FIG. 2 - the same, longitudinal section; FIG. 3 is a longitudinal section of a modified device; FIG. 4 - longitudinal variation of the second modification;

no fixture; FIG. 5 - the same, side view; FIG. b - longitudinal section of the third modification of the device; FIG. 7 - also, side view; FIG. 8 is a vertical section through a fourth modification of the device.

In order to adjust the tension of the drive belt, it is proposed to use a rotary oil can 4 (Figs. 1 and 2), and the sleeve J should be equipped with several eccentric holes 5 in case of wear, in one of which holes axis 2 is placed.

According to a modification of the invention (Fig. 3), the pulley 7 is mounted on the tube b, which is mounted on the cylinder 7, which rotates on the ball bearings 8 to is lubricated through the lubricator 4. The stem JO with spring serves to engage the reel.

In the second modification of the device (Fig. 4 and 5), the pulley 7 is freely mounted on the roller 77, and the spring and the nut 72 serve as additional adjustment. In addition, the device is equipped with a hinge 13.

According to the third modification of the tool (Figs. 6 and 7), a roller J4 is mounted on the axis of the pulley 7, on which another roller 75 is supported with friction

on line 16, whereby the shafner 17 is connected to the axes of the rollers, and to regulate friction, the predg | 3 is the spring 18.

The fourth modification of the tool (Fig. S) provides, in order to install the reel vertically, to strengthen the disk /, 9 on the pulley axis /, and on the disk - the gasket 20 for friction.

P p with d l with m and:; found n.

to the form of making the device specified in clause 3 of the author's certificate No. 28774, which is different from the tag--: that the length of the belt tension adjustment is applied by turning the oiler 4, & sleeve, / provided with several holes For wear (Fig. 1 and 2).

2. Modification of the device specified in paragraph 1, characterized in that the pulley / fastened with tube 5, put on the cylinder, rotating ka ball bearings 8, and dp attachment

Bobbin serves spring-loaded gin 10 (Fig. 3).

3, Modification of adapt, specified in paragraph 1. I distinguish between the conditions that the pulley / loosely fitted i li //. and for the additional condition the spring serves to the guy: (fig. 4 and 5).

4. Change the adaptive specified p. 1, characterized by; / mounted on the same ss with com 14 in contact according to liner no 16 with a roller 7.5 on the axis bs

rollers and for adjustment; serves as a spring 18 (Fig. 7).

5. Modification of the adaption of the above mentioned p. 1, which means that for the installation of reels, the disk 19 is strengthened on the vertical axis of the type and on it 20 is supported to support the reels; depending on the copyright certificate of E. I. Gorbunog № 28775
